STEP 1. Using scan tool (M.U.T.-IIISE), check data list item DE: Intake Air Temperature Sensor 2.
STEP 2. Check the intake air temperature sensor 2.
STEP 3. Measure the sensor supply voltage at boost pressure sensor harness side connector.
(1) Disconnect the boost pressure sensor connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal UATS line and ground.- Voltage should be between 4.5 and 4.9 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the measured voltage between 4.5 and 4.9 volts?
Go to Step 6. Go to Step 4.
STEP 4. Check of open circuit in UATS line between boost pressure sensor connector and ECM connector.
STEP 5. Using scan tool (M.U.T.-IIISE), check data list item DE: Intake Air Temperature Sensor 2.
STEP 6. Check the continuity at boost pressure sensor harness side connector.
STEP 7. Check of open circuit and harness damage in E line between boost pressure sensor connector and ECM connector.
STEP 8. Check of harness damage in UATS line between boost pressure sensor connector and ECM connector.
STEP 9. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0098 set?
Retry the troubleshooting. The inspection is complete.
